+# Rubix-cube modelization library
+#
+# As for now the library supports basic representation of a Rubix-cube
+# The library is built for speed, most operations cost no allocations to perform.
+# This does however mean that the library is NOT thread-safe and should be handled
+# with the appropriate mutual-exclusion mechanisms to avoid memory corruption
+# or unintended side-effects on a single cube.
+#
+# The library supports the singmaster notation as a way to perform operations
+# on a Rubix cube.
+#
+# No solver is (yet) provided along with the library.
